I teach for Silent World, and we run 30ft Island Hoppers with a max capacity of 14 people.
As far as the Spiegel---yes it is definitely a AOW dive (especially in December with the seas tend to be a tad rough). If you don't have your AOW, you may consider getting it while on your dive vacation and make the Spiegel your deep dive. Another option would be to hire a guide/DM/Instructor to accompany you on your dive.
